The induction of cancer by chemicals as presently understood involves a series of steps, some of which require the passage of time. Many substances that are potent carcinogens in experimental animals are known to exist in nature and occur as part of the human diet. In addition, many of the substances that are known to inhibit experimental carcinogenesis also exist in the human diet. Thus, in addition to industrially produced carcinogens, humans can be presumed to have evolved in an environment that contains both carcinogens and anti-carcinogens. There is also a great deal of experimental and human epidemiologic data on the influence of lipids, proteins and carbohydrates on cancer incidence rates; however, much of those data are confusing and conflicting.
